I seem to remember Pegasus used to multi-task pretty well, both when downloading new messages and when sending messages. For a while I've noticed that I can still do other activities while I'm downloading, but if I upload a big message, Pegasus appears to be locked up solid. Often it doesn't even update its progress indicator message for most of the upload time. It does eventually finish uploading and unfreeze.
I originally starting seeing this in 4.41. Then I finally got sick of the long-lines-wrapping bug in 4.41 and went back to 4.31, and it's still doing it there. I just switched from XP to Vista and that didn't change anything either.
Nothing has changed in my ISP connection. Other utillities (e.g. ftp) can upload at full speed without hanging. I have no outgoing-mail virus scanner.
What might have caused this to change? How can I prevent Pegasus from hanging while uploading?
Thanks,
Gary
